Is there an error message when you click the'Next' button?

If there is no error message, you need to wait for a while, it may be because you have a large number of tables.

There is no error message on click of the Next button just the application gets hanged, I have waited for 10mins and if I check the IDE logs I am seeing freeze errors. Attached the threadDump in the issue itself.

Does the earlier version of the plugin work properly, eg: 2.0.6?

The plugin is trying to load the driver:

Can you change a driver version?

Can you change a driver version? I have tried with 19, 20, and 21versions can you suggest some other version to try? Also, can you tell me how much time to wait should I wait more than 5minutes?

I don’t think this is a plugin problem, maybe you can try to upgrade the version of IDEA.

You also can try search in Google: java.lang.ClassLoader.findBootstrapClass blocked

Using the latest version of IDEA only, maybe the plugin is unable to handle huge data. Is there any kind of pagination or lazy loading implemented while pulling the database metadata?

This is not a small workload, it may take a long time to develop... you can try to use IDEA Ultimate, the plugin supports to generate code through the Database Tool

harikesh409 commented 3 years ago

Okay, I will try with the Ultimate edition.
